INVERTER MMA WELDING MACHINE
UNSMINI-120BSD

These fan‑cooled machines adopt 2‑PCB design and IGBT‑based inverter control for MMA and scratch‑start TIG welding. They auto‑adjust optimal start‑stop parameters by set current, with booster circuit improving cellulosic arc ignition and delivering powerful DC‑MMA welding across broad current range.
Arc machines suitable for a wide range of applications and electrode types such as: General purpose、Stainless steel、Cellulosic (Increase the No-Voltage)
